What about coming to stay?

What Von Braun, Ley and Bonestell first postulated in both, The Conquest of Space (1949) and Conquest of the Moon (1953), that the lunar surface would be permenantly inhabited by mankind by the end of the century, was taken up in 1975's World Book Encyclopedia Science Annual.

What form would the infrastructure on the Moon take? The Annual's nice portrait shows pods as pieces of an ever-growing base constructed over time and sailed to the Moon. Doubling as pieces of the new lunar base, these pods each serve different functions, including agriculture: a greenhouse, and indeed all farmland, would be required to be indoors.
